The purpose of this paper is to analyze theoretically and empirically spillover effects of fishery quota on related markets through their demand curves. Theoretically, the spillover effects of a change in quota can be captured through the directly distorted market alone by computing surpluses associated with the new and old equilibrium. This study estimates empirically demand functions in the context of both the partial equilibrium and general equilibrium. The spillover effect can be computed from the difference between these two estimates. The econometric methodology to estimate the demand curves in the context of general equilibrium is presented and illustrated. The empirical result of fishery markets shows that spillover effects transmitted across other markets are not small and approximately account for 43.3% of the partial equilibrium welfare effects.

경제의 장기균형은 경제에 존재하는 모든 기업들이 '초과이윤 = 0'의 조건을 충족하는 상태이다. '다른 모든 변수들이 불변'(ceteris paribus)이라는 가정에 근거한 전통적 부분균형분석은 장기균형과 논리적으로 상충한다. '산업완결균형'(full industry equilibrium)은 전통적인 부분균형분석보다 포괄적인 부분균형의 틀 속에서 개별 산업의 장기균형을 다룬다. 산업완결균형에 대한 비교정태분석은 개별 기업/산업에 대하여 기존의 부분균형분석이 도출하는 결과들이 성립하지 않을 수 있음을 보인다. 본 논문은 산업완결균형의 배경과 의의를 소개한다. 이 과정에서 산업완결균형 분석과 1960-70년대의 자본논쟁이 갖는 유사점과 상이점을 논의하고, 산업완결균형 분석의 비판적 의의와 건설적 의의를 밝힌다.

The concepy of positive aging describles the adverse effects of age on the lifetime of units. Various aspects of this concepts are described in terms of conditional probability distribution of residual life times, failure rates, equilibrium distributions, etc. In this paper we will consider some partial ordering relations of life distribution under residual life functions and equilibrium distributions.

A formulation to perform static equilibrium and linear vibration analysis is presented in this paper. The formulation employs minimum number of equations of motion which are derived by using a partial velocity matrix. The static equilibrium analysis is performed first, then the linear vibration analysis is performed at the static equilibrium position. By using the formulation presented in this paper, static equilibrium and linear vibration analysis of a high speed electric train system are performed. A single bogie system, a power car vehicle, and a train system which consists of five vehicles are analyzed, respectively. Natural frequencies and a few lowest mode shapes of the two are identified in this paper.

Adsorption characteristics of volatile organic compounds(VOCs) by activated carbon fiber(ACF) were investigated using a continuous system for benzene, toluene, xylene(BTX) generation. Studied characteristics for adsorption were equilibrium capacity, accumulative adsorption, and breakthrough curve. Operating variables were adsorption temperature(25~45$^{\circ}C$) and partial pressure(1.2~12 mmHg) of BTX. The experimental results show that the adsorption equilibrium capacity increases with increasing partial pressure of BTX and decreases with increasing temperature. It was also found that the break point was decreased with increasing partial pressure, temperature and gas flow rate due to an effect of mass transfer of adsorbate.

This paper reports an analysis of self-pressurization in a closed cryogenic liquid storage system and its comparison with experimental data using liquid nitrogen. Partial equilibrium model(PEM), revised thermodynamic analysis of homogeneous model, has been applied for the pressurization in a closed tank. The vapor and liquid bulk temperature and the liquid-vapor interface temperature are separately calculated as their own representative values in this analysis. The analysis results of the partial equilibrium model are compared with the experimental data and other preceding homogeneous temperature models for validation.

Characteristics of a plasma reactor for partial oxidation of methane, especially focused on the role and effectiveness of plasma chemistry, is investigated. Partial oxidation of methane is investigated using a rotating arc which is a three dimensional version of a typical glidingarc. The rotating arc has both the characteristics of equilibrium and non-equilibrium plasma. Non-equilibrium characteristics of the rotating gliding arc can be increased by rotating an elongated arc string attached at both the tip of inner electrode and the edge of outer electrode. In this way, plasma chemistry can be enhanced and hydrogen selectivity can reach almost 100% that is much higher than thermal equilibrium condition. As a result, the present study enables the strategic approach of the plasma reforming process by means of appropriate reactor design to maximize plasma effect and resulting in maximized reaction efficiency.

This paper studies a partial coordination situation where a set of countries coordinate their monetary policies among themselves;while the rest of the world choose their policies independently. Using a three-country orewlapping generations model, it is shown that nash partial-coordination equilibrium does not exist. This paper also studies the partial coordination under unanticipated productivity shocks.

Lycorma delicatula는 꽃매미로 알려져 있으며, 베트남, 인도, 남중국과 같은 동남아시아의 토착 해충이다. 꽃매미는 한국에 유입되어 최근 몇 년간 급속히 퍼져 특히 과일 나무에 피해를 입히고 있다. 본 연구의 목적은 Lycorma delicatula의 사례를 이용하여 미발생 병해충 영향 분석을 위한 연구방법과 추정 결과를 제시하는 것이다. 본 연구에서는 Lycorma delicatula 발생으로 인한 농가의 직접소득감소를 측정하기 위해 부분예산(partial budget) 방법을 사용하였고, 해충 발생으로 인한 사회후생 변화를 조사하기 위해 부분균형(partial equilibrium) 모형을 사용하였다. 또한 병해충 발생 적합도를 고려한 다양한 기후 시나리오 하에서 Lycorma delicatula 발생 위험이 농가소득에 미치는 영향을 추정하였다. 기후변화가 지속됨에 따라 국내 생태계는 점점 돌발 외래 병해충에 취약해질 것으로 예상되며, 이에 따른 경제적 피해는 더욱 증가할 것으로 전망된다. 나아가 이 연구는 향후 국가 해충 방제 및 검역 시스템의 효율성 평가의 기반이 될 수 있을 것으로 기대된다.

Four models in current use for cereal grain drying, equilibrium model, Morey model, partial differential equation model and simplified partial differential equation model, were modified to be suitable for natural air drying of barley. The predicted by the four models and experimental results were compared. Three models except equilibrium model predicted moisture comtent and grain temperature very well. But equilibrium model overpredicted moisture content and grain temperature of bottom layer. The degree of prediction of the four models for relative humidities of exhaust air didn't differ much from one another and equally the four models predicted relative humidity statisfatorily. Morey model took much shorter computing time than any other models. Therefore, considering the degree of prediction and computing time Morey model was the most suitable for natural air drying of barley.
